Indonesian rider Afridza Munandar died after a crash in a MotoGP support event before the Malaysian Grand Prix at the Sepang International Circuit on Saturday.
The incident in the the Idemitsu Asia Talent Cup (IATC) race occurred when Munandar went down at turn 10 on the first lap, before the race was stopped immediately with a red flag and then cancelled.
After receiving medical attention by the side of the track, the 20-year-old was transferred to the Kuala Lumpur Hospital where he succumbed to his injuries.
"The FIM (International Motorcycling Federation), FIM Asia, Dorna Sports, and all those in the Idemitsu Asia Talent Cup pass on our deepest condolences to the family, friends and loved ones of Munandar," the race organisers said in a statement.
Munandar was one of the championship contenders heading into this weekend's finale of the 2019 IATC, having recorded two wins and four podium finishes this season.
Motorsport world shares their grief
Rival teams and riders took to social media to pay tribute to Munandar, with a distinctly muted tone among those competing at Sepang.

It is the second high-profile death in motor racing in 2019, following the tragic passing of Formula 2 driver Anthoine Hubert in Belgium in August.
He had lost control of his car and hit the barriers before American Juan Manuel Correa unavoidably crashed into him at around 250 kph at the Raidillon corner.
Hubert's Arden car was demolished in the accident and he died from his injuries 90 minutes later.
Correa, 20, broke both legs and suffered a spinal injury.
